Abstract
Benzotriazole phenols with substituents either ortho to the phenol hydroxyl group and/or para to the phenol hydroxyl group can be prepared from the unsubstituted benzotriazole phenol by coupling reactions. The ortho substituent group can be a simple alkoxy or amino group, or the ortho substituent group can be a linking group, linking the benzotriazole phenol to another benzotriazole phenol group.
Claims17
A composition comprising a substituted benzotriazole phenol with the structure of Formula I:
- wherein if R1 is an —O—R9, a —N—R9R10, a —B(OR18)(OR19) group, or a —SiR203 group wherein R9 is selected from an alkyl group, or an aryl group, and R10 is selected from a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, or a heteroatom-containing group comprising one or more oxygen, nitrogen, sulfur, or phosphorous atoms, or R9 and R10 together with the atoms connecting form a heterocyclic ring structure, each R18 and R19 is independently a hydrogen atom, an alkyl group, an aryl group, or R18 and R19 together with the atoms connecting form a heterocyclic ring structure, each R20 group is an alkyl group;
- and
- each R2, R3, R4, R5, R6, R7, and R8, independently is a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, or a halogen atom;
- and R3 is an alkyl group with 8 carbon atoms.
